Fred's comments on TS 18661-4
5.1 page 2, line 6: Is there a problem with freestanding
implementations and <math.h> and trying to access the FP exception
flags? [C23 4.0 Conformance, paragraph 7]
6.0 page 3, line 8: Why "may" for SNaN?
6.1 page 3, line 17: Can one get the extended functions without having
to get the extended types? Should there be functions for _Decimal32,
_Decimal64, _Decimal128 without having to get extended types?
6.2 page 4, line 25: Why does infinity have a higher precedence than
NaN? What about SNaN?
6.3 page 5, line 25: Why does infinity have a higher precedence than
NaN? What about SNaN?
7.* Instead of sum and error, would sum and residual be better?
"error" in the Returns section seems misleading.
7.0 page 10, line 27: Also independent of flush-to-zero mode.
